  • Radiation‚ Convection‚ and Other Losses

    The Boiler Efficiency Calculator takes into account only major energy losses‚ which typically represent 10 to 20% of fuel input. The major energy losses fall into two categories: stack losses‚ and radiation and convection losses. This section deals with the second type of losses‚ that is the heat lost to the surroundings from the warm surfaces of a boiler or high-temperature water generator.Learn More
